Title: Improvements in or relating to submersible toys
IPC: A63H23/02
Filed: 1920-01-20
Abstract: 165,135. Molloy, E. Jan. 20, 1920. Boats.-A toy submarine boat is provided with means for causing it, when placed in water, to submerge and after an interval to rise to the surface. A propelling device may also be provided which is automatically set in motion when the boat rises to the surface. The hull of the boat is made of tinplate and is provided with holes for the admission of water to, and the escape of air from, the interior. An air reservoir 40, Fig. 1, is formed in the upper part of the hull and a diamond-shaped opening is cut in its floor 41, in which two tinplate cones or pyramids 46, 47, placed base to base to constitute an expansion .chamber 48, Fig. 8, are soldered. A rubber bulb 49 connected to the air reservoir 40 by a tube 51 is housed in the chamber 48. A rod 52 representing the periscope passes through holes in the decks and through a short tube 54 into the reservoir, and its lower end has a button 56 which bears on the bulb 49. A rubber flap valve 57 is provided to allow water to enter the chamber 48, but the water can only escape through the small clearance between the rod 52 and the tube 54. In use, the rod 52 is depressed to flatten out the bulb 49 and compress the contained air into the reservoir 40, and the boat is then placed in water. The valve 57 permits the water to enter the chamber 48 freely and the boat sinks. The compression of the air into the reservoir causes the bulb to expand, but it does so slowly because the water can only escape from the chamber 48 through the space around the red 52. The boat thus remains submerged for a time, and only rises to the surface when the expansion of the bulb is almost complete. In a modification, the water can escape freely from the chamber 48, but a plug of chalk is interposed between the bulb and the reservoir 40. A valve permits the air to pass from the bulb into the reservoir, but it can only get back into the bulb by percolating slowly through the chalk. The boat may also be made to propel itself as it emerges from the water by hingeing two flaps on the sides which are drawn backwards by elastic bands. The flaps are turned to stretch the hands and are locked in this position by a latch fixed to the rod 52. The expansion of the bulb lifts the latch and releases the flaps as the boat begins to rise, and the movement of the flaps propels the boat.

Abstract: 436,266. Batteries. EXPANDED METAL CO., Ltd., and SALMON, H. P., Burwood House, Caxton Street, Westminster. Jan. 19, 1935, Nos. 1858 and 6298. [Class 53] An accumulator electrode in the form of a box filled with active material, as shown in plan in Fig. 5, is made of expanded or partly expanded metal and may be made by bending a sheet of the metal into shape and welding the free edges together. The box may be strengthened by an internal zig-zag member Z of expanded metal which may be welded at points Q to the sides of the box. The box and the member Z may be made from a single piece of expanded metal which may be provided with solid edges to form a solid bottom or other solid parts, such as connecting lugs in the completed electrode. Fig. 7 shows a modification in which a sheet of expanded metal S of small mesh is first doubled upon itself and a sheet T of larger mesh then interposed between the two portions of the sheet S. The free edges J of the sheets are then burned together and a bottom to the structure is formed by burning together the bottom unexpanded edges of the outer folded sheet S.

Title: Ultraviolet radiation detectors
IPC: G01J1/58
Filed: 1972-01-14
Abstract: 1365804 Photoconductive detectors HONEYWELL Inc 14 Jan 1972 [19 Feb 1971] 1974/72 Heading H1K A photoconductive ultraviolet radiation detector, e.g. for flame detection comprises (Fig. 4) a body of potassium tantalate 13 with two metal contacts 10, 11 deposited on an as-grown surface 12, which is the smooth external surface of a crystal unmodified by chemical or mechanical polishing; so as to form two surface barrier metal-semi-conductor junctions at the interface, a bias battery and ammeter measuring the current flow as a function of radiation incident on surface 12. Contacts 10, 11 are of identical metals establishing identical barrier potentials and may be, e.g. Cu, Ag, Ga, Au, In, Cr, Pt, Mg, Al evaporated or silk screened on the surface as closely spaced dots or an interdigital pattern (Fig. 4a). The potassium tantalate crystal is undoped and grown at constant temperature of approximately 1285-1340 C. to give low dark current and high photosensitivity. Figs. 5, 6 show photocurrent for Ga contacts at different D.C. biases, and for Cu, Ag, Au, Mg, Al contacts; all peaking at 2600-2800. It is shown that barrier potentials are established at the electrode-semi-conductor interface and that photoconductive gain peaks at a value greatly exceeding unity, while the photoresponse at the front side of the detector peaks at a higher value and shorter wavelength than that at the rear side thereof, and the response with both contacts on one surface exceeds that with a contact on each surface. It is shown also that the photocurrent response is greatly increased by the as-grown surface layer over that obtained after erosion, or cleavage to the interior material. For photovoltaic operation without external bias (i.e. operation in a fail-safe mode) it is shown that the two contacts on the as-grown surface may be of different metals to establish differing surface barrier potentials in opposition (Figs. 13-15, not shown). These contacts may, e.g. comprise Ag dots and ultrasonically soldered In rich alloy ohmic contacts, which may contain Sb and Ga. Physical theory is expounded in detail.

Abstract: 589,626. Magnetic switches; regulating switches. WEST & CO., Ltd., A., and JOHNSON, C. Jan. 25, 1945, No. 2012. [Class 38 (v)] A series of contacts, for a variable resistance, is progressively actuated by a common magnet 5 which is adapted to be moved in a path close to a series af armatures 4, respectively associated with' the contacts 2, so that the armatures and corresponding contacts are actuated as the magnet passes them. In Fig. 2, the magnet 5 is carried by an operating shaft 17, and a second magnet (not shown) is mounted diametrically opposite to the first. A disc 18 on shaft 17 has an arm 23 which engages two stops 22 to limit rotation of the magnets.

Abstract: 554,762. Vibration-dampers. AUTOMOTIVE PRODUCTS CO., Ltd., and SIMPSON, J. K. Feb. 16, 1942, No. 2024. [Class 108 (iii)] In a hydraulic vibrationdamper, a tubular piston rod carries an annular piston which divides the cylinder into two chambers of equal volume each kept full by connections through lightly loaded valves to a pressure reservoir in the piston, the two chambers being directly connected through restricted orifices with excess pressure bye passes. Tubular piston rod 13 with connecting eye 20 is guided by the ends 11, 12 of cylinder 10 having a connecting eye 18 and carries annular piston 14 forming chambers 15, 16 which communicate with one another and with the reservoir 48 in the pistonrod through passages in a valve block secured inside the piston-rod by pins 22. When the piston moves upwards, liquid flows from chamber 15 through the restricted orifice in spring-pressed valve 31 into passage 36 and past lightly loaded valve 41 into chamber 16. Valve 31 lifts for excessively rapid movements causing high pressure. Reservoir 48 also communicates through passage 37 with chamber 15, 16 to keep them full, the liquid in the reservoir being kept under pressure by a floating piston 46 subjected to two helical springs 50, 51 in series. When the piston moves downwardly, a similar action occurs, valves 32 and 40 then being operative. The spring assembly with floating piston 46 can be unscrewed from the valve block and withdrawn for filling with liquid. The top edge 53 of the sleeve 54, interposed between the springs, is visible through a slot in the tubular piston to indicate the amount of liquid between full and empty limits.
